扩展现实

延展实境（Extended reality）简称XR，是指结合了实境及虚拟的环境以及人机互动设备，是用电脑技术以及可穿戴型设备所计算，其中的X是表示变数，可以是现在或是未来的空间计算技术。其中可能包括了扩增实境（AR）、混合实境（MR）及虚拟实境（VR）^[1]以及在这些之类的区域。目的是将真实世界转换到“数字映射世界”中，并且可以与其互动^[2]^[3] 。其虚拟的程度可能从部份的感测器输入到沈浸式虚拟，都算是虚拟实境。

XR包括了许多不同的技术，从“完全的真实”到“完全的虚拟”，是Paul Milgram定义中的现实-虚拟连续系统（英语：Reality–virtuality continuum）。其意义仍然在人类经验的延展，尤其是有关存在感（由虚拟实境呈现）以及获得认知（由扩增实境呈现）。随著人机交互技术的持续进行，这些意义仍在继续的演进。

XR是快速发展的领域，可以应用在许多的方面，例如环境、行销、房地产、教育训练、维修^[4]以及远距工作^[5]。
